High-definition video conferencing is a must-have in today’s business world. Find out how Pexip* leveraged Intel VTune Amplifier and Intel® Advisor to increase performance of their world-class application by about two and a half times.

"We reached our final goal of 1080p100 [frames per second] encode in a single thread. The use of Intel VTune Amplifier and the Intel Advisor vector tool have been critical to achieving this success. The two and a half times [the] performance gain allowed us to offer more than double the capacity at the same price point. For us, that translates into a major competitive advantage."

"We very quickly prototyped our core algorithm and obtained performance considerably higher than with any other processor architecture. The Intel® C++ Compiler exploited vectorization opportunities and Intel VTune Amplifier quickly identified a threading bottleneck that was simple to fix. Porting and tuning the kernel for the Intel® Xeon Phi™ processor was quick and efficient."

"We achieved a significant improvement of almost two times—even on one core—by optimizing the code based on the information provided by Intel VTune Amplifier. Good scalability resulted from the combination of Intel Threading Building Blocks and OpenMP* parallelization techniques. We achieved over eight times the performance of the previous version on eight cores and almost eleven times [the] performance on 16 cores."

"Intel VTune Amplifier analyzes complex code and helps us identify bottlenecks rapidly. By using it and other Intel® Software Development Products, we were able to improve PIPESIM* performance up to 10 times compared with the previous software version."

"The new Intel VTune Amplifier brings even more capability to an already indispensable tool. The sampling-based call stack hotspots are excellent and alone are worthy of the upgrade. We have also been impressed by how the concurrency and Locks and Waits analyses can even provide useful data on complex applications such as Premiere Pro*."

"Where this tool really shines is profiling OpenMP* code. We were able to achieve almost linear scaling in our application thanks to Intel VTune Amplifier."

"The new interface is a joy to use. Intel VTune Amplifier gives us precise, down-to-the-metal performance data that’s invaluable for pinpointing hotspots and evaluating the effect of optimizations."

"The Intel VTune Amplifier timeline is very information intensive. It organizes the data I need to tune threaded applications."

"One of [the best features of Intel VTune Amplifier] is that it is easy to use. I did not need to read the documentation."

"Intel VTune Amplifier is essential for any serious production code if performance is key. I was able to make code run twenty times faster than our prototype version while handling five times the data load."

"Simple performance bottlenecks can remain hidden until you look for them with a good profiler. Case in point, when the National Laboratory for Scientific Computing (LNCC) high-performance computing (HPC) team analyzed the radiation scheme driver for [the Brazilian Regional Atmospheric Modeling System (BRAMS)] with the Intel VTune Amplifier performance profiler, it helped us detect redundant array initializations inside a loop. Moving these before the beginning of the loop made the driver nearly 1,500 times faster than before. Using the optimized version of the driver, we obtained approximately a 19 percent overall run-time reduction for BRAMS, an important reduction for the forecast runtime. The next step for the LNCC HPC team is to use Intel Advisor to identify regions for vectorization optimization."
